Braids Betrayal
"Liliana and Braids, sitting in a tree, K-I-L-L-I-N-G"

For original version check out the Explorer build here

Everything dies in this deck, and the goal is to gain control of your opponents key creatures and hit them hard before sacrificing them to one of many abilitys/cost with x4 Pack's Betrayal and x4 Bloody Betrayal comboed with a lot of expendable creatures to sacrifice for your own abilities if need be.

Braids, Arisen Nightmare to wear away at the life total and you sneak an attack in when possible. Ghoulish Procession adds more fodder to the field, and is really is an unexpected sleeper card in this deck especially when you get more than one out. Liliana of the Veil and Eaten Alive to take care the leftovers or for stalling with early removal.

Most of your creatures come back from the graveyard so if all else fails, sacrifice them to one of the many options, worst case being the Hostile Hostel // Creeping Inn but it gets the job done.

MTG Arena TIP: Turn on full control when attacking with the decay zombie tokens if you would like to sacrafice them to Reckoner's Bargain or Dockside Chef's ability before they leave the field.

Update

• Replaced the x2 Twinferno with x2 more of The Meathook Massacre as I kept getting overran by wide boards, so trying out this build, still might need more removal.

• While I love the x2 Gisa, Glorious Resurrector, she is not functioning as well as I hoped in the deck and is a big target, might switch her out for the Duress or something like Thrill of Possibility, but I will keep testing. 

Update 2

• Cutting Gisa, Glorious Resurrector, that lets me lower that mana to 22 and adding in a 4th Ghoulish Procession as it has a fun synergy with all the sacrificing I do, plus I kind of needed more 2 drops.

• Still testing Duress vs Thrill of Possibility

Update 3

• Dropped the Thrill of Possibility for suggested Fatal Grudge which has already tested well

• Testing lowering the Bone Splinters down to 2 from 3 as suggested, increasing the Cult Conscript back up to x4

Update 4

• Added back in Eaten Alive in place of the Bone Splinters (as suggested) since Gisa, Glorious Resurrector was removed. also increased it to x3 and lowered back down the Cult Conscript

• Adjusted the mana base slightly, one less mountain, one more swamp.

Update 5

• They banned The Meathook Massacre, not going to lie that hurts a lot...

looking into other options Burn Down the House is a little to pricy for the curve. 
other options are Choking Miasma / Malicious Malfunction / Path of Peril with the last one being the best fit out of the three and splash in black and white duel lands just in case. I really could use a 2 mana replacement though so I will keep working on it.

For now replacing the x4 Meathooks with x3 Path of Peril and x1 Reckoner's Bargain, and swapping out a couple swamps for Shattered Sanctum's

Update 6

Added Furnace Reins as its just one of the best "act of treason" type effects
